IMPROVEMENT IN SHIPPING AND UNSHIPPING HIND BOARDS T0 FREIGHT-WAGONS.

Specification forming part of Letters Patent No. 49,966, dated September19, 1865; antedated August 31, 1865.

To all whom it may concern:

Be it known that I, FREDERICK W. BisHoP, of West Haven, in the county ofNew Haven and State ot' Connecticut, have invented a new and usefulImprovement in Shipping and Unshipping the Hind or TailBoard of theFrame ofthe Box ot'F1eight-WagoIis, 85e.; and I do hereby declare thatthe following is a full, clear, and exact description ot theconstruction, character, and operation ot' the same, ret'- erence beinghad to the accompanying drawings, which make part of this speciiication,in which Y Figure l is a perspective View of the hind or rear portionot' the frame ot a wagonvboX, showing the spring-bolts, spiral springs,&c., the top plate or band being removed for that purpose. Fig. 2 is asection of the saine, cut longitudinally and vertically through theframe ot' the hind board, &c., showing the relative positions of thespringbolts, spiral springs, and the fitting ofthe upper corners.

My improvement consists in titting a pair of spring-bolts longitudinallyinto the upper rail ot' the frame ot' the hind board, with beveled outerends, and the inner ends bent downward at right angles and extended ashort dis tance below the rail, so that they may be read n ily takenhold of, both with the same hand,

and pressed together, so as to withdraw bot-h ofthe bolts, and thusrelease the fastening or unship the hind board; and in having a bowstrapof iron or other' suitable material attached to each end of the upperrail oi' the frame of the hind board, to pass onto the rear ends ot' theupper side rails of the frame to hold them from being sprung out by anyaccidental pressure, Sto.

I make all ot' the frame of the box in the usual way, as shown at A,&c., Fig. 1, except the upper rail ot the frame of the hind board. Imake the upper rail, B, of the frame of the hind board with alongitudinal slot in the upper surface, as shown at a b, Fig. l. Intothis slot I t two iron bolts, c and d, onto which I slip spiral springs,as e audf, and secure the inner ends ot' these bolts by means of twoperforated iron nuts, g and 7L, embedded iu the slot, all as shown inFig. l, and indicated in Fig. 2. I put metallic caps on the ends of thisslotted rail B in the usual way, as shown at t1 andj, Fig. l, andindicated in section in Fig. 2. I also iit on two strap or loop bands, Cand D, through which the rear ends ot' the two upper side rails pass,asshown at O and D, Fig. l, and indicated in section in Fig. 2, whichwill prevent the side rails from being sprung out so as to release thespring-bolts c and d when the wagon is loaded. I tit the spiral springse and j' so that they will operate to shoot the bolts outward and intoholes in the side rails, as shown at A A, Fig. 2, to lock or ship thehind board. Y

When I wish tonnship and let down the hind board, I take hold ofthe twoinner ends ofthe spring-bolts where their bent ends project below therail, as at m and n, Figs. l and 2, and press them toward each otheruntil each of them strikes a pimp, or any other suitable stop, when thehind board may be let or turned down on the hinges E and F in the usualway; and when desired the hind board may be turned up to the positionshown in Fig. l, when the spiral springs e andf will shoot the bolts cand d into the holes or spaces in or near the ends of the side rails, asindicated at A and A, Fig. 2, when the hind board will beproperlyshipped or secured and ready for use.

Vhat I claim as my invention, and desire to secure by Letters Patent,is-

The combination of the spring-bolts c and d with the strap or loop bandsC and D, when the whole is constructed, arranged, and fitted to producethe result substantially as herein described.
